Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The existing charging device has poor adaptability and poor universality, although the charging device can be applied to a small-capacity battery, for a large-capacity battery, the charging device can always keep a charging state because the power of the large-capacity battery in a full-charge state is larger and may be continuously larger than 40W, so that the overcharge prevention function is invalid; for the case that the charging current is a pulse current, the existing charging device cannot identify the pulse current, and accordingly cannot perform corresponding control switching on the actual pulse current. The invention sets a first preset time by designing a charging method of a battery load, and automatically cuts off the power after the first preset time is reached, so that the situation that the battery load with large capacity is fully loaded but is not cut off is prevented; and setting a first preset power, if the charging power for charging the battery load is greater than the first preset power, judging that the battery load is a high-power battery load, judging the pulse state of the battery load, if the battery load is in the pulse state, automatically powering off after the second preset time, if the battery load is not in the pulse state, indicating that the battery load is not charged in a pulse mode, maintaining the charging state and carrying out cyclic detection, automatically powering off after the first preset time is reached, if the charging power for charging the battery load is less than the first preset power, the power supply is automatically cut off after the third preset time, so that the power supply can adapt to various types of battery loads, not only can the large-capacity battery load be met, but also the battery load needing pulse charging can be adapted, the phenomenon of over-charging is avoided, and the charging quality and the use quality of the battery load can be effectively guaranteed.
Example one
Referring to fig. 1, the present embodiment provides a charging method for a battery load, the charging method includes the following steps:
s101, starting a charging state;
s102, judging whether a first preset time is reached, if so, switching to a power-off state, and if not, judging whether the charging power exceeds a first preset power;
s103, if the charging power is judged to exceed a first preset power, recording that a battery load is a high-power battery load, judging whether the battery load is in a pulse state, if so, switching to a power-off state after reaching a second preset time, and if not, maintaining the charging state; and
and S104, if the charging power is judged not to exceed the first preset power, switching to a power-off state after the third preset time is reached.
The charging method is applied to a charging device, and the charging device can be a socket device or other power supply devices. The charging device is provided with a key, when a user manually presses the key, the charging state of the charging device is started, and the charging device can realize the charging process of the battery load. If the user manually presses the key again, the charging state of the charging device is closed, and the charging device cannot charge the battery load. When the first preset time is reached, the charging state is automatically switched to a power-off state, and the charging device does not charge the battery load; the first preset time may be selected from 9 hours to 10 hours, and of course, the first preset power may be other, which is not described herein again. In this way, even if the charging device charges the large-capacity battery load, the large-capacity battery load can be fully charged within the first preset time, and the power failure can be realized under the condition of full charge.
And when the first preset time is not reached, the charging device detects and judges the charging condition of the battery load and carries out corresponding control processing.
Whether the charging power to the battery load reaches the first preset power is determined, where the first preset power may be 40W, and certainly, the first preset power may be other power, which is not described herein again. It should be noted that, as for the detection method of the charging power, the current transformer can be used for measuring the current, and the voltage of the input end is measured by the divider resistor, so as to calculate the charging power, or the voltage value of the high-precision resistor can be used for calculating the input voltage, and the flowing current is reversely calculated by the resistance value, so as to calculate the charging power.
If the charging power of the battery load reaches the first preset power, the battery load is indicated as a high-power battery load, the charging device records that the battery load is the high-power battery load, and judges whether the battery load is in a pulse state at the moment, if the battery load is judged to be in the pulse state, the charging state is automatically switched to a power-off state after a second preset time is reached, the second preset time can be selected to be 2 hours, of course, the second preset time can be other, and details are not repeated herein. If the battery load is not in the pulse state, maintaining the charging state of the charging device and performing cycle detection, and if the first preset time is reached, automatically switching the charging state to the power-off state. It should be noted that, in the pulse state detection method, in the charging process of the battery load, there are constant current, constant voltage and trickle process to satisfy the charging, and the detection condition of the charging device is recorded and corrected many times to judge the fluctuation of the voltage and the current, so that the fluctuating pulse state can be judged.
And if the charging power of the battery load does not reach the second preset power, automatically switching the charging state into the power-off state after reaching the third preset time.
In the first embodiment, a first preset time is set, and the power is automatically cut off after the first preset time is reached, so that the situation that the power is not cut off when a large-capacity battery load is fully loaded is prevented; and setting a first preset power, if the charging power for charging the battery load is greater than the first preset power, judging that the battery load is a high-power battery load, judging the pulse state of the battery load, if the battery load is in the pulse state, automatically powering off after the second preset time, if the battery load is not in the pulse state, indicating that the battery load is not charged in a pulse mode, maintaining the charging state and carrying out cyclic detection, automatically powering off after the first preset time is reached, if the charging power for charging the battery load is less than the first preset power, the power supply is automatically cut off after the third preset time, so that the power supply can adapt to various types of battery loads, not only can the large-capacity battery load be met, but also the battery load needing pulse charging can be adapted, the phenomenon of over-charging is avoided, and the charging quality and the use quality of the battery load can be effectively guaranteed.
Example two
Referring to fig. 2, in the second embodiment, providing the third preset time includes a first preset off time and a second preset off time, and after the step of determining that the charging power does not exceed the first preset power, the method further includes:
s201, judging whether the battery load is a high-power battery load, recording the pulse state of the battery load if the battery load is judged to be the high-power battery load, switching to a power-off state after first preset off-time is reached, and switching to the power-off state after second preset off-time is reached if the battery load is judged not to be the high-power battery load.
After the charging power is judged to be not higher than the first preset power, whether the battery load is a high-power battery load is judged, if the battery load is judged to be the high-power battery load, the charging device is judged to be charged by taking a pulse state as the battery load at the moment, the pulse state of the battery load is recorded, and the charging state is automatically switched to a power-off state after the first preset off-time; if the battery load is not determined to be a high-power battery load, it indicates that the battery load does not need to continue to be in the charging state for a long time, and the charging state is automatically switched to the power-off state after a second preset off-time, which may be 60 seconds, although the second preset off-time may be other, which is not described herein again.
When the charging power is less than the first preset power, the charging device switches between the constant current, the constant voltage and the trickle or the state itself fluctuates, for example, the charging device is in soft start and slowly rises to charge at the full power within several seconds to several minutes in the charging process, or the state is switched until the constant voltage and the trickle are charged, the charging power output is very low, and the charging power change under the condition is allowable, it is necessary to judge whether the battery load is a high-power battery load, so that the judgment result is more accurate, the automatic switching between the charging state and the power-off state is realized in the most appropriate time, and the condition that the wrong judgment is caused and the wrong switching is avoided.
EXAMPLE III
Referring to fig. 3, the third embodiment provides that the first preset off time includes a first preset off sub-time and a second preset off sub-time, and after the step of recording the pulse state of the battery load, the method further includes:
s301, judging whether the charging power exceeds a second preset power, if so, switching to a power-off state after the first preset off sub-time is reached, and if not, switching to the power-off state after the second preset off sub-time is reached.
After the pulse state of the battery load is recorded, the charging power is smaller than the first preset power, and it is further determined whether the charging power exceeds a second preset power, where the second preset power may be 3W, and of course, the second preset power may be other power, which is not described herein again. If the charging power exceeds the second preset power, it indicates that the charging state needs to be continuously maintained, and the charging state is automatically switched to the power-off state after the first preset off-time is reached, where the first preset off-time may be 2 hours, and of course, the first preset off-time may be other times, which is not described herein again. If the charging power does not exceed the second preset power, it indicates that the battery load is not connected with the charging device, if the battery load is arranged on the battery car, it indicates that the plug at the end of the battery car is in a disconnected state, and the charging state is automatically switched to a power-off state after the second preset disconnection sub-time is reached, where the second preset disconnection sub-time may be 300 seconds, and certainly, the second preset disconnection sub-time may be other, which is not repeated herein. However, it should be noted that the first preset time is longer than the second preset off sub-time.
Example four
Referring to fig. 4, after the step of determining that the battery load is in the pulse state is provided in the fourth embodiment, the method further includes:
s401, judging whether the charging power is abnormal in fluctuation or not, if so, sending an alarm signal, and if not, maintaining the charging state.
After the battery load is judged to be in a pulse state, whether the charging power fluctuates abnormally is further judged, if the charging power fluctuation is judged to be abnormal, an alarm signal is sent out immediately, and the specific implementation mode can be that an alarm lamp is turned on to remind a user of eliminating the abnormality before. If the charging power is judged not to be abnormal in fluctuation, the charging state can be maintained and the cycle detection can be carried out. It is worth mentioning that the charging power fluctuation in different charging states is not considered as a fluctuation abnormality in the same pulse detection manner.
In the actual charging process, if a plurality of battery loads are connected to the charging device, or if an interface connected to the charging device on the battery loads is loosened, the charging power fluctuation is abnormal. And the fourth embodiment can carry out alarm processing by judging the charging power so as to prevent the charging failure and even burn out the charging device, thereby ensuring the charging quality of the battery load.
EXAMPLE five
Referring to fig. 5, the fifth embodiment provides that the charging method further includes the following steps:
s501, after the first preset time is judged to be not reached, whether the battery load is connected or not is judged, and if not, the battery load is switched to a power-off state after the fourth preset time is reached.
After the first preset time is judged to be not reached, whether a battery load is connected or not is further judged, and if the battery load is judged to be connected, whether the charging power exceeds the first preset power or not is continuously judged. If it is determined that the battery load is not connected, the charging state is automatically switched to the power-off state after a fourth preset time, where the fourth preset time may be 10 seconds, and of course, the fourth preset time may be other, which is not described herein again. Through the judgment of the connection state of the battery load, the condition of idle charging of the charging device can be avoided, and the charging device can be switched to a power-off state in time when the battery load is not connected with the charging device.
It should be noted that, for the judgment of the connection state of the battery load, whether the battery load is resistive, inductive or capacitive, the voltage change and the load change after the voltage is applied to the output end can be detected by detecting the voltage of the output end, and the battery load connection can be detected.

If the user manually presses the key again, the charging state of the charging device is closed, and the charging device cannot charge the battery load. Through the judging unit 102, when the first preset time is reached, the charging state is automatically switched to the power-off state, and the charging device does not charge the battery load; the first preset time may be selected from 9 hours to 10 hours, and of course, the first preset power may be other, which is not described herein again.

When the charging power is less than the first preset power, the charging device switches between the constant current, the constant voltage and the trickle or the state itself fluctuates, for example, the charging device is in soft start and slowly rises to charge at the full power within several seconds to several minutes in the charging process, or the state is switched until the constant voltage and the trickle are charged, the charging power output is very low, and the charging power change under the condition is allowable, it is necessary to judge whether the battery load is a high-power battery load, so that the judgment result is more accurate, the automatic switching between the charging state and the power-off state is realized in the most appropriate time, and the condition that the wrong judgment is caused and the wrong switching is avoided.
Example eight
Referring to fig. 8, in an eighth embodiment, the first preset off-time includes a first preset off-time and a second preset off-time, and the high-power battery load determining module includes:
and the second preset power judgment submodule 301 is configured to judge whether the charging power exceeds a second preset power, switch to the power-off state after the first preset off-time is reached if the charging power exceeds the second preset power, and switch to the power-off state after the second preset off-time is reached if the charging power does not exceed the second preset power.
After the pulse state of the battery load is recorded, the charging power is smaller than the first preset power by the second preset power determining submodule 301, and it is further determined whether the charging power exceeds the second preset power, where the second preset power may be 3W, and of course, the second preset power may be other, which is not repeated herein. If the charging power exceeds the second preset power, it indicates that the charging state needs to be continuously maintained, and the charging state is automatically switched to the power-off state after the first preset off-time is reached, where the first preset off-time may be 2 hours, and of course, the first preset off-time may be other times, which is not described herein again. If the charging power does not exceed the second preset power, it indicates that the battery load is not connected with the charging device, if the battery load is arranged on the battery car, it indicates that the plug at the end of the battery car is in a disconnected state, and the charging state is automatically switched to a power-off state after the second preset disconnection sub-time is reached, where the second preset disconnection sub-time may be 300 seconds, and certainly, the second preset disconnection sub-time may be other, which is not repeated herein. However, it should be noted that the first preset time is longer than the second preset off sub-time.
Example nine
Referring to fig. 9, the ninth embodiment provides that the judging unit includes:
and a fluctuation anomaly determination module 401, configured to determine whether the charging power fluctuates abnormally, if so, send an alarm signal, and if not, maintain the charging state.
After the battery load is judged to be in a pulse state, the fluctuation abnormity judgment module 401 further judges whether the charging power fluctuates abnormally or not, and if the charging power fluctuation is judged to be abnormal, an alarm signal is sent out immediately. If the charging power is judged not to be abnormal in fluctuation, the charging state can be maintained and the cycle detection can be carried out. It is worth mentioning that the charging power fluctuation in different charging states is not considered as a fluctuation abnormality in the same pulse detection manner.
In the actual charging process, if a plurality of battery loads are connected to the charging device, or if an interface connected to the charging device on the battery loads is loosened, the charging power fluctuation is abnormal. In the eighth embodiment, the alarm processing can be performed by judging the charging power, so that the situation that the charging fails and even the charging device is burnt down is prevented, and the charging quality of the battery load is ensured.
Example ten
Referring to fig. 10, the present embodiment provides that the judging unit includes:
the battery load determining module 501 is configured to determine whether a battery load is connected after determining that the first preset time is not reached, and if not, switch to a power-off state after a fourth preset time is reached.
After the battery load determining module 501 determines that the first preset time is not reached, it is further determined whether a battery load is connected, and if the battery load is determined to be connected, it is continuously determined whether the charging power exceeds the first preset power. If it is determined that the battery load is not connected, the charging state is automatically switched to the power-off state after a fourth preset time, where the fourth preset time may be 10 seconds, and of course, the fourth preset time may be other, which is not described herein again. Through the judgment of the connection state of the battery load, the condition of idle charging of the charging device can be avoided, and the charging device can be switched to a power-off state in time when the battery load is not connected with the charging device.
It should be noted that, for the judgment of the connection state of the battery load, whether the battery load is resistive, inductive or capacitive, the voltage change and the load change after the voltage is applied to the output end can be detected by detecting the voltage of the output end, and the battery load connection can be detected.
